UE4：静态网格体模拟物理选项为灰色怎么办
在虚幻引擎中，静态网格体的模拟物理选项为灰色怎么办？ 很简单，造成这个选项灰色的原因是该静态网格体没有碰撞，解决办法为：双击点开静态网格体，点击上面的碰撞菜单，按照实际需求添加碰撞，保存，再回来看就会发现模拟物理选项已经可以点击了。 官方解释： If true, this body will use……
【PYQT】How to modify the Label text and attributes in PYQT Design by clicking the button
The purpose of this article is to use pyQt Design to create a graphical Python GUI. When a button is clicked, the text content of a TextLabel changes
Use VS CODE as the compiler, and install PYQT Integration plug-in for graphical. UI compiles, converts.ui into.py, and any other compiler compiles pyQt in the same way
How do I solve the problem that the touch screen and display screen of the Windows operating system are inconsistent
Recently, I encountered a problem: when I use a touchscreen display, the touch function is mapped to my large screen, not the secondary screen, but the touchscreen is actually on the secondary screen. What should I do to solve this problem?
First of all, it should be clear that the misaligned touch screen is not a hardware problem, but a software configuration problem, and Windows offers a perfect solution:
Step 1: Open the control panel

[Unreal4] Get virtual camera image in unreal engine and import it into UI(UMG) for UI camera real-time display
Objectives: Real-time acquisition of virtual camera lens images in Unreal Engine and display in GUI, similar to left and right rearview mirrors display images in racing games, or real-time acquisition of camera image information display in GUI interface, or real-time capture of camera images in VR.
Test version: 4.26 (universal for most versions)
Knowledge needed:
1. SceneCaptureComponent2D
2. CanvasRender target material (CanvasRenderTarget2D)
3. Image module in UI
Function implementation approach: to obtain a virtual camera image real time display and import the UI, you need a real-time capture images and convert them into dynamic material, real-time images were obtained through the scene capture the component 2d flow, converts the render target material to ordinary material, finally to create the image in the GUI, and give the image for the module material.

windows的触摸屏和显示屏不一致怎么办
最近遇到一个问题：当我用带触摸屏功能的显示屏时，触摸功能映射到的是我的大屏，而不是副屏，但是触摸屏其实是在副屏上的，遇到这种触屏错位问题的时候，应该怎么解决呢？
首先要明确，触屏错位并不是一个硬件问题，而是软件配置问题，而windows提供了完善的解决方法：
第一步：打开控制面板
联想thinkpad R14拆解+升级内存+升级固态
最近博主用上了thinkpad R14（i5-10210u/8G/256G铠侠固态+1000G西数机械/AMD Radeon 625+集显/FHD/Win10），是一台很一般的联想thinkpad笔记本电脑，放上它的拆解图。
拆机很简单，就是卸掉底盖的全部螺丝，在机身上下盖处开始翘，有一圈卡扣，拆除后盖即可看到主板，升级内存，升级固态。
硬盘升级：机器配有NVME 2280固态硬盘接口X1 SATA3固态硬盘接口X1，如果你的电脑购买时没有配置SATA接口的机械硬盘，可以直接升级一块SATA固态硬盘（左下角）
内存升级：注意本机只有一个内存接口……要想升级只能买昂贵的单条16G或32G一步到位，原厂自带一条8G DDR4 2666三星内存（本机），没有板载内存。
热管比较粗，但是压独显+CPU还是挺难的，整机运行起来动不动就80℃+了，还是不是很适合玩大型游戏的。
